To a, whom it may concern.-

Be it known that I, JAKOB CORZILIUS, a citizen of Germany, residing atPaterson, in the county of Passaic and State of New J ersey, haveinvented certain new and useful Improvements in Looms, of-which thefollowing is a specification.

This invention relates to that class of looms which are designed forWeaving double-pile i'o fabrics for the production of plushes, velvets,carpets, and similar pile fabrics. In looms of this class the objectionwas heretofore encounteredthat the weft or filling was not drawn tautand straight from selvage to selvage, so that the cross-grain of thepile fabric was formed irregular and uneven, rendering the sameunsightly. To overcome this latter defect, my invention consists in twotension devices arranged one at each side of the lay, which tensiondevices act upon the Weft-threads after they are shot across by theshuttle and clamp the same against the end dents of the reed as the laybeats the same up.

The invention also consists of certain details of construction andcombinations of parts to be hereinafter described andthen particularlyclaimed.

In the accompanying drawings, Figure 1 is a side elevation of myimproved loom. Fig. 2 is a side elevation of the main portion of myinvention, parts being in section, the lay being shown as in itsrearward position before the weft or woof is beat up. Fig. 3 is a 3 5side view of the same parts, showing the lay in its forward position.Fig. 4 is a detail front elevation looking toward the lay. Fig.

5'is a transverse section on line 5 5, Fig. 4;

and Fig. 6 is an enlarged detail on same section-line.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the frame of the loom, B B thetwo beams for the linen warps b b, and O is the beam for the pile-warpc, which is conducted over guiderollers The lay D is oscillated from thepower-shaft D through the medium of .a connecting-link d in the usualmanner, while the :heddles E, by which the warp-threads are shifted ,soas to make the sheds ff for the passage of the shuttles, are of theusual construction, and are operated in the usual manner by mechanismWell understood.

In connection with the loom tension devices are arranged at each side ofthe lay which act to hold the weft or filling taut after, the same ispicked across the shed by the shuttles S S and while the lay is movingforward-for beating up the weft or filling threads. These tensiondevices consist of a movable bar K, which is pivoted to a bracket on thelay and carries at its upper end a springactuated U-shaped or groovedshoe or presser device K, while at the other side of the lay is anotherpivoted bar K (see Figs. 4 and 5,) which is also provided at its upperend witha grooved or U-shaped spring-actuated presser -shoe K Each shoehas a shank K, which is guided in a suitable guide K at the upper end ofits carrying-bar K, between 5 which guide and a stop or abutment K onthe shank K is arranged the contractingspring K, which tends to hold theshoe in forwardly-projected position. The presser shoes K K are arrangedin the same transverse line at each side of the lay, but extend parallelwith the dents Z of the reed L, some of the dents Z being cut out atl ateach end of the reed L, so as to form recesses into which the flanges ofthe presser-shoes of the tension devices can move. Both of the tensiondevices are underthe tension of springs m, fixed to a suitable portionof the frame A of the loom. By means of its spring m the tension deviceK is always held in position toward the lay, but is prevented fromfurther movement toward the same, as is also the other tension device Kby means of stops n, projecting from adjustable stop-bars N, so that gothe presser-shoes K K will not move into the sheds ff to interfere withthe proper picking of the shuttles. Said tension devices K K as soon asthe lay takes its natural forward movement and reaches the same aremoved 5 forwardly with the lay against the tension of their springs; butas the lay is returned said tension devices K K are returned with thelay under the actuation of their springs, but are prevented from movingthrough the entire return stroke of the lay by means of the said stops01, against which the bars K K come in contact. the subsequentdescription that the tension devices K K need not both move directlyinward with the lay; but one of the same may be caused to dwell or pauseat an intermediate point of its inward movement. To effect this purpose,a latch O is pivoted to a bracket 1 on a beam P of the frame A, whichlatch is provided with a recess 0. Near the free end of the latch isformed an inclined shoulder 0 which moves upon a plate d on the lay D,so that when the lay is moved forward, and with it either of the tensiondevices is moved and shortly after the lay commences the returnmovement, the shoulder on said tension device engages in the recess 0 onthe latch O with the result that the tension device is locked in outwardposition and does not return with the lay. When, however, the plate d onthe lay reaches the shoulder 0 the latch is raised thereby, the tensiondevice released, and returned to inner position through the actuation ofits spring. A similar latch mechanism is arranged at each side of theloom, so that both of the tension devices may be latched and caused topause during the return stroke of the lay, or only one may be latched,as maybe desired. When the lay has moved up to the tension devices afterthe simultaneous pick of the shuttles from opposite sides of the loom,the springs m press the shoes K K into the end dents of the reed, so asto draw the filling or weftthreads w taut between the same, while thelay beats the filling up against the built-up fabric W. The filling isthereby held taut across the fabric and a more perfect pile fabricproduced. The filling-threads running from the respective shuttles willthus be held by a tension-shoe on the same side of the loom as theshuttle, while at the opposite side of the loom the filling-thread willbe bound around the selvage. I-Ieretofore the lay beat up the fillingand when it returned the filling would be retained at the fell as heatup and would be drawn ofi the shuttle, so as to run along the selvage,so that when the lay beat up the filling again after another pick eitherthere would be too much filling or else the filling would be so laid inthat puckering would result. In the present invention this objection isovercome on the return stroke of the lay, as the tension devices act asdrags, so as to exert a pulling action on the filling, and inconsequence, therefore, the tension devices can be designated drags.During the return stroke of the lay the combined tension and dragdevices pull out some of the filling which runs to the shuttlesdiagonally from where it It will be apparent from was beaten up at thefell, and the amount pulled out can be regulated by calling one or bothof the latches 0 into action, so that one or both tension or dragdevices may be caused to pause and only a small portion-that is tosay,fellof the pre viously-beat-up filling will be drawn out again. Ifthe latches are not in use, still more of the filling will be drawn out,until the dragging or pulling action is limited by stops at. This actiondoes not cause the opposite selvages of the fabric to be drawn tight orpuckered, as the whole transversely-running filling lap or length is notdrawn out. In this way only the required length of filling is used, asthe portion running from the shuttle to theopposite side of the fabricwill be shorter than if it were not pulled out by the dragging action ofthe combined tension and drag devices. It will of course be evident thaton the next beat of the lay the filling partly drawn out will be beat upagain to form the fell, and on the return the described action will takeplace. Having thus described my invention, what I claim is- 1. In aloom, the combination, with the reed of the lay, of tension devices,means for holding the same away from the lay, during the pick of'theshuttles, and means for moving said tension devices to ward the lay,when the same moves forward to beat up the filling, said tension devicescooperating with the end dents of the reed, substantially as set forth.

2. In a loom, the combination, with the reed of the lay, of tensiondevices, means for holding the same away from the lay, during the pickof the shuttles, and springs connecting the tension devices and lay, formoving said tension devices into the end dents of the reed, when the laymoves forward to beat up the filling, substantially as set forth.

3. In a loom, the combination, with the lay and the shuttles, of pullingor dragging means acting on the filling between the lay and fell so asto draw it away from the fell, when the lay is moving back,substantially as set forth.

4. In a loom, the combination, with the lay; of a tension device,consisting of a movable rod provided with a U-shaped shoe for theweft-threads, cooperating with the end dents of the reed, and means forcausing said tension device to meet the lay when the same moves forwardto beat up the filling, substan tially as set forth.

5. In a loom, the combination, with the lay, of tension devices for theweft-threads cooperating with the end dents of the reed of the lay, andstops'for holding said tension devices in retracted position away fromthe reed during the pick of the shuttles through the shed, substantiallyas set forth.

6. In a loom, the combination with the lay, and a plate extendingtransversely of the same, of tension devices for the weft-threadscoeperating with the end dents 0f the reed, my invention I have signedmy name in pres pivoted latches constructed with shoulders ence of twosubscribing witnesses. and recesses, said latches resting upon the plateon said lay, and shoulders on the ten- 5 sion devices adapted to engagethe recesses Witnesses:
